Our &#8220;enemies&#8221; are usually third world countries without an air force, so the thought that they could pose a threat is preposterous and an insult to our military. Our navy and air force is number one, no one will touch us, not Russia, Korean, or Chinese. If all our troops are at home, then the enemy would have to fight an abroad, overseas war, which would not end up well for them, so they wouldn&#8217;t attack us in the first place. The only people that want to attack us are our victims.
